External beam radiotherapy (EBRT) is a standard treatment for prostate cancer. Despite the development of novel radiotherapy techniques such as intensity-modulated conformal radiotherapy, the risk of local recurrence after EBRT has not been obviated. Various local treatment options (including salvage prostatectomy, brachytherapy, cryotherapy, and high-intensity focused ultrasound [HIFU]) have b...

Brachytherapy is a modality of treatment available for lung cancer with tracheal involvement. Correct positioning of the brachytherapy catheter is vital to the optimisation of treatment effect and reduction of complications. Normal airway anatomy and tumour location can make this positioning difficult. The current study presents the case of a 65-yr-old male with invasive tracheal squamous cell ...

PURPOSE To report the treatment effect of image-guided high-dose-rate (HDR) interstitial brachytherapy for refractory recurrence of papillary thyroid cancer (PTC). CASE REPORT This 66-year-old female presented with recurrence 5 years after thyroidectomy for PTC. Despite external irradiation and radioactive (131)I, the lesion expanded as 3.7 × 3.0 × 2.3 cm(3) and 2.0 × 1.5 × 1.5 cm(3). The loc...

BACKGROUND We aimed to investigate the effects of brachytherapy, drug-eluting stent (DES) and bare metal stent (BMS) applications in the treatment of coronary artery disease, on five-year clinical outcomes and mortality. METHODS Two hundred and seventeen patients who were treated in our clinics between January 2000 and December 2003 with brachytherapy, DES, or BMS for both de novo and in-sten...

Brachytherapy results in better dose distribution compared with other treatments because of steep dose reduction in the surrounding normal tissues. Excellent local control rates and acceptable side effects have been demonstrated with brachytherapy as a sole treatment modality, a postoperative method, and a method of reirradiation. Low-dose-rate (LDR) brachytherapy has been employed worldwide fo...

Quon and Harrison have performed a considerable service to patients with head and neck cancers by reminding the oncology community that a state-of-the-art treatment team must include state-of-the-art brachytherapy. A fundamental adage in radiotherapy is "If you don’t hit it, you can’t cure it." Modern tools of external-beam radiotherapy, such as intensity-modulated radiation therapy, allow us t...

BACKGROUND Radiotherapy (RT), short-course androgen deprivation therapy (ADT), and brachytherapy in various combinations are treatment options for patients with intermediate-risk prostate cancer (PC), but the question of which combination if any is necessary to minimize PC-specific mortality (PCSM) risk in patients with favorable or unfavorable intermediate-risk PC is unknown. The authors asses...

OBJECTIVES Some patients are medically unfit for or averse to undergoing a brachytherapy boost as part of cervical cancer radiotherapy. In order to be able to definitively treat these patients, we assessed whether we could achieve a boost plan that would mimic our brachytherapy plans using external beam radiotherapy. METHODS High dose rate brachytherapy plans of 20 patients with stage IIB cer...
